This is a nice installation from Nokia. A digital panel in the shape of arrow was lifted 50 metres above London by a crane. People on the street could send text messages directly to the live sign with their favorite places to visit, and the arrow would move to point to that location, and also provide the distance!

The installation was streamed live to Nokia.com, where all the locations were synced with Nokias good things map. A great way to promote their geo-localization for mobile OVI Maps.

1) Rather than using the biggest, brightest ad to talk at us, this thing encourages — rather, requires — that we talk with it. The brand is inviting consumers to participate, and our data fuels the ad. It’s such a fine line — take away that user-powered interactivity, and suddenly this sign seems like just another over-sized billboard that merely accomplishes to mar the skyline and assault the eye, like so much out door advertising in the world. But this signpost dodges that bullet by offering useful information in a fun way, and by working with the consumer.

2) This is just the coolest blend of old and new media, analog and digital.
